The AFL's new match review officer Michael Christian handed down the decision on Monday afternoon, the first use of the AFL's revised match review system.

"Ordinarily it would have leant itself to being low impact, but I've decided to upgrade the impact to medium with the potential to cause a more serious injury," Christian explained to reporters on Monday afternoon.

"Sarah Hosking was distressed but she was able to get up, take her kick and play on."

D'Arcy and Collingwood are expected to accept the two weeks with an early guilty plea, leaving her available for the club's round four clash with Melbourne.
